Gerucht is dus dat er een nogal groot lekje in de current IOS'jes zit, en
dat dit morgen bekend gemaakt gaat worden. Als dit echt zo is, kan dit nog
wel eens leuk worden.

Iemand meer info?

Hello All,

There seem to be rumors going around that there is a new major Cisco vulnerability but only the major backbones are being given fixes right now.

Something about packets malformed in a certain manner cause the router to wedge.

Can anyne shed any light on or off list?
